The solar energy heating cellular construction
Technical field
The utility model relates to that a kind of collecting efficiency is high and safe in utilization, easy-to-install solar energy heating cellular construction.
Background technology
Along with the development of modern industry and society, human society is strengthened day by day for the dependence of the resource and the energy.And well-known, the tellurian resource and the energy are limited, so the effective of the resource and the energy utilized into matter of utmost importance, solar energy is the human the abundantest utilizable energy.
In recent years, solar water heater has entered huge numbers of families, and in the heat utilization of solar energy, key is that the radiant energy with the sun is converted to heat energy.Because solar energy relatively disperses, and must manage it is put together, so heat collector is the various key components of utilizing solar energy equipment.Solar water heater of the prior art comprises support, heat storage water tank and the vacuum heat collection pipe that connects water tank.After this vacuum heat absorbing pipe receives solar energy, utilize cold water than the heavy principle of hot water, and produce the phenomenon that cold water is dirty, hot water rises, and then make the liquid in the described vacuum heat absorbing pipe reach free convection circulation heating.The shortcoming of prior art is: owing to rely on the water in the heat storage water tank to store solar thermal energy for using, the heat storage water tank volume is big, Heavy Weight, cost height; All the time be full of water in vacuum tube and the water tank, seepage arranged easily, leaking causes damage, particularly cold district uses and have freeze proof hidden danger winter, even brings about great losses.
The utility model content
It is little that the technical problems to be solved in the utility model provides a kind of heat accumulation volume, heat accumulation temperature height, storage density greatly, do not leak hidden danger, collecting efficiency is high and safe in utilization, easy-to-install solar thermal collection system components and parts, can constitute the solar energy system of different scales, the object that satisfies different temperatures and heat uses.
The utility model solves described problem by the following technical solutions:
A kind of solar energy heating cellular construction, comprise refractive body and heat-collecting heat-storage element, described heat-collecting heat-storage element skin is an all-glass vacuum thermal-collecting tube, be sealed with composite phase-change heat-storage material in the described all-glass vacuum thermal-collecting tube, and U-shaped heat exchanger tube that passes through for heat-transfer working medium or the heat pipe that is used to conduct quantity of heat given up are set.
Further, the cross section of described refractive body is the compound parabolic wire; The internal layer of described all-glass vacuum thermal-collecting tube scribbles high temperature resistant selective heat-absorbing rete.
Further, described U-shaped heat exchanger tube is made of copper.
Solar energy heating cellular construction described in the utility model, owing to utilize the interior tube chamber of all glass vacuum heat collecting directly as the heat accumulation place, being transferred to need local by heat-transfer working medium when needing directly uses, can save or reduce the heat storage water tank of existing solar water heater and system, and owing to adopt phase-change heat-storage material, when the all-glass vacuum tube breakage appears, when leaking gas, falling problems such as film, not influencing complete machine and system uses, more can not cause the phenomenon such as icing of metalling run out, guarantee to use the security of solar energy; Owing to adopt compound parabolic wire refractive body, have spotlight effect more efficiently, the vacuum tube usage quantity is reduced, system simplification, simple installation further promotes temperature.
